Title: Mechanism for end cropping and producing test samples from welded seam tubing
IPC: B23D45/12
Filed: 1958-07-14
Abstract: 828,596. Cutting-off lathes; mandrels. ETNA MACHINE CO. July 14, 1958 [April 2, 1958], No. 22546/58. Class 83 (3). A device for end-cropping and producing a test sample from lengths of welded seam tubing comprises a roller conveyer R, Fig. 1, which feeds a non-rotating-tube T to a stop in a housing C, said tube being clamped at A and severed by a rotating cutter-head B. In operation, the tube T, Fig. 2, is fed through a collet-chuck 10, 11 in housing A, passes over an inside colletchuck 14, 15 and engages a stop 16. Chuck 10, 11 is actuated to clamp the tube, after which chuck 14, 15 is expanded to grip the inside bore of the sample to be cut, Fig. 3. Cutters 12, 13 in the rotating cutter head move radially inward to crop the end EC and produce a sample TS. The cutters are then retracted radially and collet 10, 11 releases the tube, which is then withdrawn, and collet 14, 15, carrying the testsample and the cropped end, is moved to the right past stop 16, which is moved upwardly, the sample and cropped end being ejected after the collet 15a has been released. Another tube is then inserted in collet 10, 11, and the sequence of operations repeated. The mechanism may be electrically-operated and the cycle of operations energized by contact of the tube with stop 16. Cutters 13 preferably complete their cut before cutters 12, so that the sample remains supported by collet 10 as long as possible. The amounts of end-crop may be varied by adjustment of stop 16.

Filed: 1929-05-11
Abstract: 334,919. Groves, W. W., (I. G. Farbenindustrie Akt.-Ges.). May 11, 1929. Divided on and addition to 334,878. Thioindigo series.-The stable reduction compounds of 4: 4<1>-dimethyl-6 : 6<1>-dihalogenthioindigos described in the parent Specification are made by treating the dyestuffs with alkali and a reducing agent, other than a hydrosulphide, and causing an acid, for instance carbonic acid or sulphurous acid, to act on the solution thus obtained. The reduction may be facilitated by the addition of an alcohol to the reaction mixture. In an example, 4: 41-dimethyl-6: 6<1>-dichlorthioindigo is reduced with hydrosulphite and caustic soda in the presence of alcohol and water; carbon dioxide is then passed through the mixture until it is no longer alkaline to phenolphthalein.

Abstract: 843,805. Sensing record cards. FERRANTI Ltd. July 17, 1958 [July 19, 1957], No. 22921/58. Class 106 (1). [Also in Group VIII] Apparatus for sensing record cards having conductive marks, e.g. of pencil comprises means to clamp the card against a plate 20, Fig. 3, carrying an array of contacts arranged in groups of two or three, one or two 55, 56 of each group being connected to a voltage source and the other one 50 being connected to an output terminal to deliver a signal when it is connected with one or both of the live contacts by a mark on the record card. The cards may be pre-printed with guide marks to facilitate placing the pencil marks. As shown in Fig. 1, the card is clamped against plate 20 by a clamp plate 21 displaced to clamping position against the action of springs 48, 49 by a solenoid 28 acting through a system of links. When the card is properly in sensing position it closes a micro-switch to energize the solenoid 28. The contact plate 20 is of an insulating material and the voltage supply wires 53, Fig. 4, are arranged in parallel grooves 52 in the rear, the outer contact wires 55, 56 passing through the thickness of the plate and being connected to wires 53. The middle contacts 50 are arranged in a similar way but are merely formed with a terminal at the rear. Between groups of sensing contacts, Fig. 3, are vertical guide wires 57 designed to protect the sensing contacts. The terminals of contacts 50 are connected to terminals 100, Fig. 5, of a number of ganged switches. If there are three hundred sensing positions there may be twelve banks each having twenty-five terminals 100 scanned in turn by wipers 101. The signals from contacts 50 are amplified at 102 and entered serially into twelve shift registers and transmitted from these to other equipment. The " answer '' signal from this equipment is applied to the control magnets 87, Fig. 1, of a punch combined sensing machine to punch the answer into the card being sensed.

Abstract: 280,327. Airship Guarantee Co., Ltd., Burney, C. D., Wallis, B. N., and Temple, J. E. Sept. 17, 1926. Aerostats; cabins.-In a rigid airship comprising longitudinal girders and polygonal frame mem. bers, in order to provide for the conditions arising when one gasbag is deflated, the radial bulkhead wires are so arranged that some of them are initially taut and connected direct to the frames, while the remainder are initially slack and are connected to catenaries slung from the frames, all of them being connected to an axial restraint member which transmits axial forces to the longitudinal girders. The slack wires G, Figs. 1 and 2, are connected to catenaries H, which together with the taut wires F are connected to the frames A at the points where they cross the longitudinal girders B. The end of a taut wire F and the adjacent catenarv ends mav be located within a socket-piece H<1>, and provided with adjustable turnbuckles. The axial restraint member may be of stranded wire, but is shown as a triangular space frame girder C built up by means of spiders E, Fig. 9 carrying sockets e' to which the tubular members are connected by coupling rings. Each spider supports a shaft e<2> carrying a hub D to which the wires F, G are secured as shown in Fig. 9, and which have bollard-pieces d supporting cables d<1> for fuel tanks, ballast or the like. The gas-bags are axially apertured to receive the girder C. Netting J is interlaced with the bulkhead wiring, and netting I covers the gaps between the catenaries H and the periphery of the gas-bag netting. A connection may be made to the circumferential mesh wiring of the gas-bags at the point where the catenaries join the frame-members which may be by means of a strop or the like as in Specification 281,041. If the centroids of the longitudinal girders and the frame members are coincident, the lift and shear wires may be attached at the centroids as in Specification 282,167. The axial girder may be used for control leads, or as an access passage, and a corridor L, Fig. 1, may be provided. The degree of slackness of the wires G is progressively greater from the bottom to the top of the airship.
